Ambient, constant lighting is preferable to direct and/or time-varying lighting, since the latter increases the risk of overexposure and underexposure. For indoor acquisition, fixed lights are preferable to flash, and for outdoor acquisition, clouds (high-altitude cirrus clouds, no rain) are preferable to sun. If photos must be taken on a sunny day, take them around noon to minimize shadow areas.

Please note that correctly-exposed shadows do not affect the performance of ContextCapture , but will appear in the texture map of the generated 3D model.
